Top euro zone countries see Iran inflation fallout broaden in May

Euro Zone Inflation Trends and Economic Impacts

FRANKFURT, May 29 (Reuters) - Inflation in the euro zone's four largest economies hovered above the European Central Bank's 2% target for a third straight month in May, preliminary data showed on Friday, as a rise in fuel costs triggered by the Iran war began to feed through to other prices.

Readings from France, Italy, Spain and Germany are likely to cement the case for a rate hike from the European Central Bank next month and stoke some worries about whether high inflation is beginning to take root in the euro zone.

Country-Specific Inflation Developments

Both Spain and Italy reported strong increases in the price of transport and entertainment activities, a likely sign of the knock-on effect of higher fuel costs. Measures of underlying inflation rose both in Italy, to 1.8% from 1.6%, and in Spain, to 2.9% from 2.8%. France saw a 4.1% jump in the cost of fresh food and a slight increase in services inflation.

Expert Commentary on Inflation Outlook

"We are not at the peak yet," said Nadia Gharbi, a senior economist at Pictet Wealth Management, who expects euro zone inflation to rise until August. "A lot will depend on the situation in the Middle East and we have as a baseline that the situation will normalise by the end of June."

Oil Prices and Their Influence on Inflation

Hopes of a deal to end the war between the United States and Iran have pushed oil prices down  substantially since the end of April, with a barrel of Brent crude selling for $92 versus $118 back then. Still, prices remain well above the around $70 a barrel level seen just before the war. 

Headline Inflation and National Variations

A Relatively Mild Inflation Wave

Headline inflation was more of a mixed bag. National gauges of price growth rose in France, to 2.8% from 2.5%, and in Italy, to 3.2% from 2.7%, but remained stable in Spain at 3.2% and fell to 2.6% from 2.9% in Germany, which implemented a fuel discount for May and June as part of a package to cushion the impact of higher petrol prices.

"Today’s inflation numbers should not be read as a sign that the inflation wave is already over before it actually started but rather as a confirmation that this is a relatively mild inflation wave," said ING's economist Carsten Brzeski.

Euro Zone-Wide Data and Core Inflation

Euro zone-wide data due on Tuesday is expected to put headline inflation at 3.3% in May, with a core gauge excluding energy, food, alcohol and tobacco at 2.4%.

"This information so far hints at a further rise in headline inflation, and some increase in core inflation," JPMorgan economist Raphael Brun-Aguerre said in a note.

Manufacturing Prices and Historical Context

France continued to see deflation in manufacturing prices, strengthening the view that the current inflation shock should be smaller than the one that followed the COVID pandemic and Russia's invasion of Ukraine in 2022, according to Bersingeco economist Sylvain Bersinger.
